Bias against homosexuality has led to research conclusions, as you mentioned, that favor heterosexuality because heterosexuals are the privileged majority. This is WRONG. It still doesn't make the question of why? any less scientifically interesting (to me, at least).

It's been a few years since this has been filmed. I'd like to see a remake, letting those fun bags swing in the breeze over the last 2 years should have improved the flop. The more they sag the better they bounce and flop. I love saggy tits her size.
